Hadc.init.clockprescaler

Web0. I'm trying to convert 3 ADC channels using DMA. But the variables don't seem to change when I watch them in the debugger. I know the conversion complete callback is executed because I breakpointed it. So this suggests that the DMA transfer is not executing and the buffer is not being filled. I'm using stm32cube to initialize my project.

WebHi @VDutt.1 (Customer) and @DJack.8 (Customer) . From your code samples, I see you do not use the same STM32 MCU, but your issue is similar. Note for Doug: STM32L0 and STM32F4 ADC have not the same features: on STM32L0, channel rank in the sequence cannot be configured, it is fixed to channel number. WebI'm using the ADC channels (12-bit resolution) of a STM32F0 microcontroller to read voltage values in three different points of a board. What I want to do is to read the values every 2 seconds (I have 2 seconds to read the values in the three points) and send them by the UART interface.

Webfirst i think you should be aware of some thing like configuration. these are the Steps to configure the ADC in the DMA mode. 1. Enable ADC and GPIO clock. 2. Set the prescalar in the Common Control Register (CCR) 3. Set the Scan Mode and Resolution in the Control Register 1 (CR1) 4.
